BACKGROUND OF THE INVENTION

The present disclosure relates to a telescoping pullout for a pulloutguide which is extensible and retractable in a furniture body. Thepullout guide has a fixed guide rail, which is fixed by at least onefastener on the furniture body.

A telescoping pullout guide is known in many embodiments. In a simpleembodiment, it still contains a pullout guide fixed on the pullout,which is guided by the fixed guide rail during extension and retractionof the pullout. However, in order that the pullout can be pulled nearlycompletely out of the furniture body, pullout guides having a so-calledmiddle rail, which is also movable in relation to the guide rail and isguided thereby, are also known.

The furniture body can be a cabinet, but can also be the housing of ahousehold appliance, such as a dishwasher, a refrigerator, or the like.Depending on the type of the furniture body, the pullout is designed asa drawer, a basket, or a similar tray, for example.

In the pullout guide, the guide rail and the pullout rail, andoptionally also the middle rail, comprise steel. In the pullout guidesknown up to this point, the connections between the fasteners and theguide rail are formed by welded-on angles. This solution, which isknown, is subject to the disadvantage, however, that surface-coatedcomponents may not be used, for example, if they are lacquered, powdercoated, or provided with a zinc coating.

The present disclosure relates to a telescoping pullout guide designedin such a manner that welded-on connectors can be dispensed with, sothat profiles or rails which are already provided with a surface coatingmay also be used.

The pullout guide, according to the present disclosure, includes aconnection between the guide rail and each fastener that is formed fromat least one angled web, which engages in a perforation and overlaps theadjoining edge area, and a securing web inserted into an opening.

A pocket is formed by each angled web, into which the area adjoining theperforation is inserted. In order that the guide rail is secured againsta displacement in the pullout direction of the pullout, the securing webis also shaped or pressed into an opening. A further advantage occurs inthat the surface coatings of the rails of the pullout guide and thefasteners may be different.

In a first embodiment, it is provided that each angled web is formed byshaping of a notch provided in the guide rail. Using a suitable tool,this notch and the shaping can be produced in one work step. A furtheradvantage occurs in that no waste arises. Because the guide railcomprises steel, cold shaping is possible.

It is further provided that each angled web, in relation to theinstalled location of the pullout guide, is shaped from the lower leg ofthe guide rail. The lower leg of the guide rail can be in the plane ofthe floor or parallel and at a distance thereto in the case of a pulloutin the form of a drawer.

In a further embodiment it is also provided that the free leg of eachangled web overlaps the area of the guide rail adjoining theperforation.

Furthermore, it is provided that each fastener is connected to the guiderail by at least two spaced-apart angled webs. The guide rail istypically connected via two spaced-apart fasteners, so that theconnection is produced as a whole by four angled webs.

For easier insertion of the fasteners into the pocket delimited by theangled webs, it is provided that the end area of each free leg of theangled web is angled to form an insertion bevel.

To secure the guide rail against the pullout direction of the pullout,it is also provided that the securing web is transverse to the centrallongitudinal axis of the guide rail. In an embodiment, the securing webengages in an opening. The securing web engages in an opening which isprovided in the guide rail. Each securing web is formed, according tothis embodiment, by deformation of a web remaining between twopunched-out areas in the leg of the fastener.

In a another embodiment, the fasteners may be implemented as fasteningangles. The leg associated with the guide rail is connected thereto inthe way already described, so that the other leg presses against thefacing surface of the furniture body. The connection to the furniturebody can be performed by screws, for example. If the furniture bodycomprises metal, suitable connectors may also be used, such as rivetsand the like. These fastening angles may be connected to the guide railin such a manner that the contact leg is laterally adjacent to the railsystem or is oriented downward.

In a further embodiment, it is also provided that the above-describedconnection between the guide rail and each fastener can also be used inorder to receive a pullout part movable out of the furniture body, forexample, if the furniture body is part of a refrigerator. The body ofthe refrigerator is to remain unchanged. It is therefore provided in afurther embodiment that the fastener for the telescoping pullout guideis implemented as a holding plate, whose edge areas are fixed ondiametrically opposing walls of the furniture body.

In this embodiment, it is possible that the intermediate floor, which isprovided for subdividing the refrigerated space, or the floor itself isused in a refrigerator to fix the pullout guide thereon, for example.

In this embodiment, it is provided that the holding plate has theperforations, in which the angled webs of the guide rails engage, in theedge areas. In this embodiment, the legs of the fastening anglesperpendicular to the side walls of the furniture body are replaced bythe edge areas of the holding plate.

To fix the edge areas of the holding plate, it is advantageouslyprovided that the edge areas of the holding plate are each fixed on atleast one holding web, which is fixed on the side walls of the furniturebody. These connections may be designed so that the holding plate isfixed in a formfitting and/or friction-locked manner inside thefurniture body.

However, the side walls which delimit the refrigerated space of arefrigerator are typically provided on the sides facing toward oneanother with two spaced-apart holding webs, into which the edge areas ofintermediate floors are insertable. It is therefore provided in afurther embodiment that the edge areas of the holding plate are fixed ina formfitting and/or friction-locked manner in a slot formed by twospaced-apart holding webs. This can be achieved, for example, by acorresponding thickness of the holding plate. The connections betweenthe edge areas of the holding plate and the two lower legs of the guiderail are identical or approximately identical to the connections usingthe angled fasteners.

Other aspects of the present disclosure will become apparent from thefollowing descriptions when considered in conjunction with theaccompanying drawings.

Pullout guide 10comprises a pullout rail 11, which is extensible, a middle rail 22, anda guide rail 12, which is fixed on a furniture body (not shown) by twofasteners in the form of fastening angles 13, 14. For example, a drawer(not shown) is fixed on the pullout rail 11. For this purpose, thepullout rail 11 is equipped with a holding angle 15 and a front stop 25in the pullout direction. FIG. 1 also shows an end location damper 24. Aconnection of the guide rail 12 to angled webs 16, 17 is explained ingreater detail hereafter.

The embodiment according to FIGS. 2 and 3 shows pullout guide 10 havinga pullout-extending middle rail 22, which is extensible by a specificamount. FIG. 2 shows that a lower leg of the guide rail 12 is providedwith angled webs 16, 17. These angled webs 16, 17 are formed by notches,the material areas delimited by the notches being shaped into the angledwebs 16, 17. An associated leg of the fasteners 13, 14 is provided withperforations 18, 19, through which the angled webs 16, 17 may be guided.After displacement of the guide rail 12 in the pullout direction, theseangled webs 16, 17 overlap adjoining edge areas and form an undercutagainst lifting off. This is recognizable in FIG. 4. Furthermore, asshown in FIG. 4, two punched-out areas 20, 21 are provided in an endarea of each leg of the fastening angle 13, 14, which are separated fromone another by a securing web 26. In the course of the manufacturing ofthe pullout guide 10, this securing web 26 is deformed and engages in anopening (not shown) of the guide rail 12. Securing in the longitudinaldirection of the guide rail 12 is thus provided.

As suggested, for example, in FIGS. 1-4, the fasteners in the form ofthe fastening angles 13, 14 are connected in a formfitting andfriction-locked manner to the guide rail 12. The pullout-extendingmiddle rail 22 allows an over-extension.

FIGS. 3-5 suggest that the angled webs 16, 17 penetrate the perforations18, 19, and the free end area of the free leg is bent over to form aninsertion bevel. The free end areas of the angled webs 16, 17 engagebelow the edge areas formed by the perforations 18, 19.

FIGS. 6 through 8 show an embodiment in which two telescoping pulloutguides 10 are fixed on edge areas of a holding plate 23 in the same wayas on the fastening angles 13, 14. FIGS. 6-8 suggest, for example, thatthe angled webs 16, 17, which are shaped out of the legs of the twoguide rails 12 and facing toward one another, engage below the holdingplate 23. The pullout guides 10 correspond to those of FIGS. 1 through5.

FIG. 6 shows that the pullout guides 10 are at a distance to outerlongitudinal edges of the holding plate 23, so that the lateral edgeareas may be fixed on holding webs of the furniture body (not shown).FIG. 7 shows that each pullout guide 10 comprises the pullout rail 11,the guide rail 12, and a pullout-extending middle rail 22. FIG. 6 alsoshows that each pullout guide 10 is equipped with an end location damper24.

FIG. 8 shows that the edge areas of the holding plate 23 are eachprovided with four perforations 18, 19 situated at a distance to oneanother, in which the angled webs 16, 17 are configured to engage in theway already described. Also shown are perforations 27.

The edge areas of the holding plate 23 are inserted into slots, whichare attached or shaped onto the side walls of the furniture bodydelimiting the refrigerated space, for example, in a way not shown. Apullout part, for example, a drawer, can be fixed on the pullout guide10 via the pullout rail 11 in a way not shown.

FIG. 9 shows an embodiment, according to the present disclosure, inwhich the telescoping pullout guide 10 is fixed on the fasteners 28, 29in the same way as on the fastening angles 13, 14.

The angled webs 16, 17, which are shaped from the legs of the two guiderails 12 facing toward one another, engage below the fasteners 28, 29.The pullout guide 10 corresponds to those of FIGS. 1 through 5. Thefasteners 28, 29 are configured for the floor installation of a pulloutguide 10 in a body of a refrigerator, for example.

FIG. 10 shows an embodiment, according to the present disclosure, inwhich the telescoping pullout guide 10 is fixed on the fastening angles30, 31 in the same way as on the fastening angles 13, 14.

The angled webs 16, 17, which are shaped from the legs of the two guiderails 12 facing toward one another, engage below the fastening angles30, 31. The pullout guide 10 corresponds to those of FIGS. 1 through 5.The fastening angles 30, 31 are configured for side wall installation ofa pullout guide 10 in a body of a refrigerator, for example.

According to the present disclosure, it is important that angled webs16, 17, which are formed through deformation by notches in the legs ofthe guide rails 12, are situated on the guide rails 12. Each fastener13, 14 is provided, for example, with two perforations 18, 19, and mayalso be provided with perforations 27. Furthermore, it is important thatpunched-out areas 20, 21 are provided in the fasteners 13, 14, which areseparated from one another by a securing web 26, which is shaped into anopening of the guide rail 12 by deformation. The securing against thepullout direction of the pullout guide 10 is thus achieved.
